Hand Bending
Bending is the operation manual replacement.Bending is the operation manual replacement. In most cases the hand of narrow cold-bending of sheet metal, rods and płaskowników held in vice by using hammers. Hot bending is carried out on the anvil. For bending in the vice should be used with metal inserts in the shape angle. Vices, clamps jaw inserts to protect against damage and also zapieniają obtain bending angle equal 90 degrees. In order not to damage the surface płaskownika its direct impact hammer is applied to the line of bending another piece płaskownika, in which directly hits the hammer. If there is a need for a small bending radius of the sheet and cut from the sheet of commercial, in which it is difficult to determine the direction of the fibers, then you need to check the minimum bending radius. If the bending radius is smaller than the calculated, you must bend to the heat, that it does not rupture the material. Manual tube bending requires adequate preparation of the pipe bending, and the bending is carried out often in the instrument. Thin-walled tube bending is particularly difficult due to the distortion of the pipe cross section. Distortion is the greater, the smaller the bending radius and a lower ratio of pipe wall thickness to its diameter.
